Polystyrene-supported GaCl3 was prepared from polystyrene and gallium trichloride. This reagent was used as a new Lewis acid catalyst for preparation of N-substituted pyrroles by an one-pot condensation reaction of 2,5-hexanedione with amines and diamines. This new protocol has the advantages of easy availability, stability, reusability and eco-friendly of the catalyst, high to excellent yields, simple experimental and work-up procedure
